7 7 The unique modular level switch system What you need... Trimod Besta s modular design is a unique deviation from conventional level switch construction. This modular system allows individual and numerous combinations of float, flange and switch modules to suit your specific requirements. Switch modules are available with electric, electronic or pneumatic output signals. Switch housings are standard to IP65 enclosure, but depending on environmental conditions IP66, IP67 or IP68 must be chosen. For hazardous areas, hermetically sealed microswitches, flameproof housings or pneumatic switch modules can be used.... is quickly installed... Trimod Besta flange modules are available in various standards. The Industrial and Plastic Flange ranges are manufactured according to international standards such as EN/DIN, ANSI, BS or JIS. The benefit of the hinged cover, the captive screws and the selflifting terminal clamps is an easy installation. For convenience of wiring, the connection diagram is shown on the inside of the hinged lid. The interchangeability of the single modules allows high flexibility regarding maintenance or changing application requirements.... and lasts forever. So far, hundreds of thousands of Trimod Besta level switches are on duty world-wide. The float movement caused by the rise and fall of the liquid level is transmitted by two repelling, permanent AINiCo magnets. The sturdy design and the double snap effect as a result of the magnetic repulsion and the snap action of the microswitch guarantee a virtually unlimited lifetime. The float modules, like all wetted parts, are made of stainless steel, Hastelloy C or high quality plastics. A wide range of floats is available to suit various viscosity-, temperature- and pressure ranges for almost any process condition.

10 10 Typical Standard Range switches to handle the majority of applications The characteristic of a Trimod Besta level switch of the Standard Range is the square flange in stainless steel with bolt holes on a 92 mm PCD and a nominal pressure rating of PN 25. The following pages show the level switches which are most commonly used. However, countless more combinations of types are possible. Detailed information can be found on all the modules available with the possible combinations on pages 21 to 36. For accessories, such as test actuators, counterflanges and float chambers see pages 38 to 42. Typical applications: shipbuilding, refrigeration, chemical engineering, food industry, pulp and paper, drinking water supply, sewage treatment etc. Type A For general purpose Nominal pressure Operating temperature Ambient temperature Density of liquid Operating differential Rod extensions Wetside material Flange material Housing material Flange dimensions Counterflange Switch element PN 25 max. 25 bar up to 300 C 0 to 300 C 0 to 70 C min. 0.7 kg/dm³ fixed 12 mm see page 36 Stainless steel (CrNiMo) Stainless steel (CrNiMo) Sea water resistant die cast aluminium square 92 x 92 mm, PCD 92 mm see page 38 Microswitch SPDT with silver contacts Switch rating Enclosure Weight 250 VAC, 5 A IP65 approx. 1.8 kg 30 VDC, 5 A Safety Integrity Level (SIL) SIL 1 (Type AA 01 04: SIL 2) Type A Low cost solution This type is the same as the A but there is no possibility for mounting a rod extension.

For pump control (two switch points): The required differential is set by fixing the two stop collars in the appropriate positions on the rod. The counterweight is adjusted to compensate for the rod weight (without float), until the cross arm is balanced. The float slides up and down the rod with the liquid level and actuates the switch at the set position of the stop collars. The switch remains latched between the two positions, which are for applications such as pump control where the contactor coil would need to remain energised throughout the pumping cycle. counter weight Stop collar 2. For alarm duty (one switch point): Only the lower collar is fixed on the rod (below the float). Within the limit of the rod length, the height of the alarm point can be chosen as required. The counterweight has to be set to outweigh the rod (without float). The alarm switching differential is 12 mm, fixed. Installation Over open tanks or sumps on a bracket. On closed tanks on the manhole cover with float mounted from the inside. In the absence of a manhole, i.e. the float cannot be mounted from the inside, an intermediate flange of at least DN 125/5 should be used. If turbulence occurs, the rod should be guided loosely at the lower end. For counterweight setting, refer to data sheet LTDS02EN.

17 17 The Industrial Range offers numerous flange combinations The main feature of the Industrial Range is the wide choice of flange modules, manufactured according to international standards such as EN/DIN, ANSI, BS or JIS. Available in various steel qualities, nominal sizes and pressure ratings (e.g. up to PN 320 acc. to EN/DIN or class 2500 acc. to ANSI). Shown here are only a few typical combinations, many more possibilities can be found in the module descriptions. All types in the Standard Range shown on the previous pages can of course also be combined with industrial flanges. Frequently used on off-shore rigs, in steam boilers and plants, power stations, chemical and petrochemical engineering, heating and refrigeration, i.e. airconditioning technology.

Following are four typical examples, but these are by no means the limit of possible combinations which can be specified by reference to the module descriptions on pages 21 to 35. Vacuum Applications: For vacuum duty a modified sealing must be used, suffix to flange code is E20, e.g. A 301E This must be specified in the purchase order.

27 27 Flange modules The flange module is selected according to the required flange standard, nominal pressure rating (PN), nominal size (DN), type of gasket, properties of the medium and flange material. A basic distinction is made between flange modules for the Standard Range, the Industrial Range and the Plastic Range. The flange modules may be installed either horizontally or vertically. Pressure equipment directive (PED) 97/23/EC: For switches according to directive 97/23/EC add the letter «P» after flange name, e.g. A 01P 041 Table 14 Flange modules for the Standard Range Type Standard flange 01 Square flange incl. gasket Material Nominal pressure PN 25, max. 25 bar up to 300 C Flange facing Raised face Temperature range -196 to 300 C Counterflange see page Round flange incl. gasket Material Nominal pressure PN 25, max. 25 bar up to 300 C max. 23 bar at 400 C Flange facing Raised face Temperature range -196 to 400 C Counterflange see page 38 Type Special flanges 03 Round flange incl. gasket Material Nominal pressure PN 25, max. 25 bar up to 300 C max. 23 bar at 400 C Flange facing Raised face Temperature range -196 to 400 C 04 Round flange incl. gasket Material Nominal pressure PN 25, max. 25 bar up to 300 C max. 23 bar at 400 C Flange facing Raised face Temperature range -196 to 400 C 06 Round flange incl. gasket Material Nominal pressure PN 25, max. 25 bar up to 300 C max. 23 bar at 400 C Flange facing Raised face Temperature range -196 to 400 C

38 38 Accessories Counterflanges with and without test actuator The simplest method of installing any Trimod Besta level switch of the Standard Range and the Compact Switch with a square flange, is to use our standard weld-on counterflanges. There are carbon steel (P250GH) and stainless steel (1.4404) versions in two different lengths available. The test actuator allows a periodic manual function check of the level switch in operating status. The function of the switching element (microswitch, proximity switch, pneumatic valve) and movement of the float can be tested.

39 39 Counterflange with test actuator Important: Positioning of counterflanges with G 3/8 thread for test actuator. If the level switch is used for high alarm the thread has to look upwards. For a low level alarm, the thread has to look downwards.

40 40 Float chambers Wherever it is not possible or desirable to install float switches directly onto a vessel, horizontal Trimod Besta level switches can be mounted externally in a float chamber. This type of installation allows functional checks and servicing to be carried out without interrupting operation, provided that isolation and drain valves are included in the process connections. Float chambers may be divided into 2 groups. Standard chambers PN 25 In various steel qualities and configurations with process connection acc. to EN/DIN or ANSI. For use with the Trimod Besta level switches from the standard range with: Square flange type: 01 or Round flange type: 011 Industrial chambers up to PN 320 acc. to EN/DIN or PN cl acc. to ANSI In various steel qualities and configurations with switch- and process connections acc. to EN/DIN or ANSI. For use with the Trimod Besta level switches from the industrial range with EN/DIN-flanges DN 65 or ANSI-flanges DN 3.
